Fig 1. Characteristic histopathological findings observed in postmortem
examination.
A, pulmonary dysplasia in gross; B (the contralateral lung), C (the
ipsilateral lung) Relatively normal lung development bilaterally was
showed in left CDH , hyaline membrane formation in the alveolar space,
diffuse pulmonary hemorrhage, widened alveolar septa were found
((hematoxylin and eosin (HE), × 200); D (the contralateral lung), E (the
ipsilateral lung) underdeveloped lung structure at canalicular period in
both lungs showed in right CDH with decreased number of alveoli, and
diffuse alveolar edema and hemorrhage with hyaline membranes, marked
inflammatory cell infiltration were found (HE, × 100); F, lung structure
development was fair, alveolar hyaline membrane was found(TTF-1, × 200);
G, pulmonary hemorrhage, hemosiderin cells found in the lung (HE, ×
200); H, aplasia of the musculature within the leaflet of the
ipsilateral diaphragm (HE, × 100); I, ipsilateral diaphragm
calcification necrosis, inflammatory cell infiltration in right CDH (HE,
× 200)
